tiling onto old tiles

[Andy the tiler]

I am starting a job shortly and the customer wants her new tiles set onto the old ones.Its only 6 m2 in the kitchen.Should I pva or prime first? Its my 1st job and I want it to look good. I,m using Larsen fast set adhesive,will 20kg be enough? And evostick teknik grout,will 5kg be enough? thanks

Personally , i would pull the old ones off first...

Also is there any exposed edges , if so you will see 2 thicknesses of tile..

 

[Andy the tiler]

no problems with exposed edges,she just wants them laid ontop.Do you think my quantities for adhesive and grout are enough,thanx

 

[DHTiling]

Quantities ok...Are the old tiles glazed..?

:yikes::yikes::yikes: deffo not pva, make sure existing tiles are degreased and spotlessly clean. I've never used the adhesive you mentioned so I can't comment, but 5kg of grout will be ample

I think they are glazed.They are about 10 years old so nothing too modern or fancy. Also looked at evostick pourable thickbed from advise by another tiler,thats wot he recommended. Its 3 times the price but I,ll ask the customer.

Pourable thick bed.....??..Are we talking walls or floor here..?

 

[Andy the tiler]
